Your HVAC system works hard all year long to keep your home comfortable. But if you’re noticing a dip in performance, especially in cooling, it might be a sign of a refrigerant leak. Refrigerant is the lifeblood of your air conditioning system, and when it starts to escape, it can lead to bigger problems if not addressed quickly.

In this post, we’ll walk you through the most common signs of a refrigerant leak, why it matters, and what you should do if you suspect one.

What Is Refrigerant, and Why Is It Important?

refrigerant is a chemical compound used in HVAC systems to absorb and release heat. It cycles through your system, changing from gas to liquid and back again, to cool your indoor air efficiently. A leak disrupts this cycle, leading to poor performance and potential system damage.

Common Signs You Have a Refrigerant Leak

Reduced Cooling Power

If your AC is running but the air coming from the vents isn’t as cool as it used to be, a refrigerant leak might be to blame. Low refrigerant levels mean the system can’t absorb enough heat to cool your home properly.

Longer Cooling Cycles

Does your air conditioner seem to run constantly without reaching your desired temperature? A leak forces the system to work harder and longer to maintain comfort, leading to increased energy bills.

Hissing or Bubbling Sounds

Refrigerant leaks often produce a hissing or bubbling noise, especially near the indoor unit or refrigerant lines. This sound is caused by refrigerant escaping through small holes or cracks.

Ice on the Evaporator Coil

Low refrigerant can cause the evaporator coil to become too cold, leading to ice buildup. If you see frost or ice on the indoor unit or around the refrigerant lines, it’s time to call in the pros.

Higher Energy Bills

When your system runs longer to compensate for low refrigerant, it uses more electricity. A sudden spike in your energy bill with no clear explanation could point to a leak.

Poor Airflow or Humidity Issues

If the air feels clammy or the airflow from your vents seems weaker than normal, it could be tied to a refrigerant issue. Inadequate cooling can make your home feel humid and uncomfortable.

Why You Shouldn’t Ignore a Refrigerant Leak

Ignoring a refrigerant leak can lead to:

  • Compressor failure, which is a costly repair
  • Inefficient cooling, making your home uncomfortable
  • Environmental damage, since many refrigerants are harmful to the atmosphere
  • Higher operating costs, due to longer system run times
